Question

You are attempting to move a 40.0 kg couch by pulling upwards and dragging the couch forward. You pull with a force of 180 N in a direction that is 30.0° above the horizontal. The coefficient of kinetic friction between the couch and the floor is 0.250. What will be the acceleration of the couch? F_pull ?

Step 1

The weight of the couch (force acting downwards) = mass x acceleration due to gravity Weight = 40 kg x 9.8 m/s^2 = 392 N The normal force (force acting upwards) = Weight - force pulling upwards x sin(30°) Normal force = 392 N - 180 N x sin(30°) Normal force = 392 Show more…
